''' We're working with a CSV file, which contains employee information. Each record

has a name field, followed by a phone number field, and a role field. The phone

number field contains U.S. phone numbers, and needs to be modified to the

international format, with "+1-" in front of the phone number. Fill in the

regular expression, using groups, to use the transform_record function to do

that. '''
